Abstract

A file transfer method for transmitting a large data file in slices from a sender to a receiver through the Internet on multiple parallel FTP connections uses the restart (REST) command of the industry-standard FTP Protocol to command an FTP server to transfer the respective slices starting with the first byte corresponding to that slice. This method can obtain the same high speed download performance of multiple simultaneous FTP connections without requiring any special software to be installed at the sender end. The “restart” file transfer method can be employed in a batch-processing system for performing file transfers from multiple FTP servers through the Internet in which each file transfer involves multiple parallel FTP connections. The batch-processing system has designated Receiver Machines for handling file transfers from any FTP server using multiple parallel FTP connections, an Autopoller Server for monitoring the status of file transfers from any FTP server to the Receiver Machines, and an Admin Program connected to the Autopoller Server providing a graphical user interface for an operator for administration of the system.

Description

[0001] This invention generally relates to Internet file transfer using the File Transfer Protocol (FTP) for downloads of large files through the Internet, and, more particularly, to an improved method for obtaining very high speeds for large file transfers using multiple parallel download connections, and to a system for batch processing and administration of such large file transfers. BACKGROUND OF INVENTION

[0002] As shown in FIG. 1, file transfers over the Internet are commonly accomplished by a sender program of one user sending data from an original file over a connection to a receiver program of another user, with the result that the receiver has a copy of the original file. For downloading a file using the File Transfer Protocol (FTP) of the TCP / IP Protocol commonly used on the Internet, as shown in FIG. 2, the sender program is a standard FTP server, the connection is an FTP connection, and the receiver program is a standard FTP client program. The process is initiated by t...
